§ The result
3 points separate Ribbon and Pin.
Ribbon holds a 3-point edge over Pin under rubric v1.0, 43 to 40, across the Screening and Sourcing cohorts. The 7 criteria split 5 to 1 in favour of Ribbon, with 1 level: Ribbon is ahead on Article 11 Technical Documentation and Pin on Post-Market Monitoring. Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing — Pin 30, Ribbon 42 — and at a 20% weight it carries 57% of the weighted advantage Ribbon holds across the 5 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -3.3 — the difference between the two totals before either is rounded. Shares are of 5.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -3 beside that -3.3.

§ Evidence
Cited sources and documented absences, criterion by criterion.
An absence is a finding, not a blank: the reviewer looked for a named artefact and recorded that it is not located. Where a source sits is a fact about hosting only.
